WHEN TO REPLACE SMR
Scratched Surface
Cleaning dust from the SMR optic with a rag or other abrasive material scratches the gold plating and diminishes SMR accuracy.
Drops and Breaks
An SMR should be replaced if it is dropped. Although API’s SMRs are break-resistant, dropping an SMR can flatten out the surface of the outer ball. An SMR with a flat spot causes centering inaccuracy.
Confidence in accuracy
Inaccurate SMRs reduce productivity and increase operator frustration and costs. Regularly check or replace SMRs to have confidence in measurement accuracy.
